openITCOCKPIT has been around for more than 15 years. Since the first release the openITCOCKPIT interface is the key component. Our mission is to create an easy-to-use, modern and responsive web frontend.
For the first time, openITCOCKPIT interface is 100% based on openITCOCKPIT API interface and runs as a single-page application. This approach is snappy and responsive and feels more like a desktop application than a web-based one.
But not only did we refactor the technical components from scratch, we also added a whole bunch of little helps to the interface. Tools such like "Create another" checkbox, a new menu structure and an optimized user routing between different actions help you to improve your daily workflow and monitoring experience.
After installing the latest security patches on your system Nagios and Naemon will most likely not work anymore. The Statusengine Event Broker which gets loaded into the monitoring core depends on the json-c library.
Unfortunately it seems like the patches that should fix security issues CVE-2020-12762 within json-c are causing the problem.
For now the easiest method is to downgrade to the old version of json-c to get your system up and running again.
As far as we know this bug only affects Ubuntu users.
